Self-locking rollers are provided on both sides of the base bottom. A motor is provided at the rear of the feeding device. A discharge port is provided below the crushing drum. A vibration motor is provided within the crushing box. A screen frame is provided below the discharge port. A revolving door is rotatably connected to the bottom of the screen frame. A screen plate is fixed to the bottom of the supporting rod via a second bolt. A discharge pipe is provided below the screen plate. A threaded column is fixed to the bottom of the crushing box. A collection frame is provided below the discharge pipe, and a collection box is provided below the collection frame. An electric valve is provided at the bottom of the crushing box.
